Sigh. In California statutes and local ordinances make almost any knife is illegal to carry, regardless of type if it has a blade much over an inch long.

So far I have not been hassled when carrying knives camping, hiking, etcetera. Nor have small knives been confiscated when going through various security, though occasionally I have the choice of forfeiting the knife forever or heading back out the door [usually there is a check-in and get-back-on-your-way-out procedure].

My point: Check local knife carry law and local practices where you go often as part of your EDC decision.
